Figure 8-23. Printhead Cleaning View
The Full Cleaning Routines (Levels 1-3) are designed to alleviate minor print defects that have
resulted from a printhead nozzle being clogged. Sometimes a bit of dry ink or dust will
temporarily block a printhead and a white line will be seen in the printed image. Occasionally a
bit of media or debris will block a printhead nozzle. When a defect like this is seen in the
printed image, run Level 1, Level 2 and then Level 3 until the nozzle is clear and the defect is
gone.
For very small defects and maintenance, the Quick clean routines can be used. These routines
spit ink through the printhead nozzles without wiping the printhead on the service tray,
whereas the printhead cleaning Level routines, spit ink and then wipe the head after the spits
as part of the routine.
Do only minimal (one or two) Quick cleans without doing a Level 1, 2 or 3 cleaning. If too much
ink runs through the nozzles without a wipe, additional nozzle clogging could occur.
It is not critical to run the cleaning routines in any particular order. The routines are ordered by
amount of cleaning, and any routine can be used at any time. Note that some, but not all,
routines require the removal of media from the printer. For these cases the user is prompted
to remove media before continuing.
A quality report can be printed after cleaning routines to view the progress of the clean. A
selection of quality reports is available on this page. Choose the one that best assists with
resolving any printing defects.
If printhead cleaning has been performed with no improvement to print quality, look into using
other maintenance routines. Contact Neuralog support if needed.
